swap-case

What is swap-case?

The swap-case npm package is designed to transform text by swapping the case of each character in a string. It converts lowercase letters to uppercase and vice versa, providing a simple and effective way to manipulate text case in JavaScript applications.

What are swap-case's main functionalities?

Swap Case

This feature allows you to swap the case of each character in a string. Lowercase letters become uppercase, and uppercase letters become lowercase. It's useful for text formatting and styling in applications.

const swapCase = require('swap-case');

let text = 'Hello World';
let swappedText = swapCase(text);
console.log(swappedText); // Outputs: 'hELLO wORLD'

Other packages similar to swap-case

change-case

The change-case package is a comprehensive text transformation library that includes various case conversion utilities such as camelCase, capitalCase, constantCase, dotCase, headerCase, noCase, paramCase, pascalCase, pathCase, sentenceCase, snakeCase, and swapCase. It offers more extensive functionality compared to swap-case, which focuses solely on swapping the case of characters.

upper-case

The upper-case package is specifically designed to convert all characters in a string to uppercase. While it serves a different specific purpose, it is related in the broader category of case manipulation. Unlike swap-case, it does not provide the functionality to swap cases but rather converts all characters to a single case.

lower-case

Similar to upper-case, the lower-case package converts all characters in a string to lowercase. It is another example of a case manipulation package but, like upper-case, does not offer the swapping functionality found in swap-case.
